Algal Growth And Decomposition: Effects On Water Quality, Phase Ii, Edward G. Foree, Ronald L. Barrow

KWRRI Research Reports

The decomposition and associated nutrient regeneration of three unialgal cultures and one mixed culture containing an indigenous population of bacteria and microscopic animals were studied under dark, constant temperature laboratory conditions. After periods of nutrient-deficient growth ranging from O to 30 days, these cultures were inoculated with decomposer populations and subjected to anaerobic and aerobic environments for the decomposition studies. The extend of decomposition was determined from the percentage volatile suspended solids and percentage particulate COD remaining after 200 days of decomposition. The average extent of decomposition was greater for aerobic than for anaerobic conditions. However, significant portions of the …

Factors Affecting Relocation In Response To Reservoir Development, Rabel J. Burdge, Richard L. Ludtke

KWRRI Research Reports

The focus of this paper is on the question of how rural people anticipate forced moves as a result of flood control projects and how they change their life in accepting separation from familiar surroundings.

A model of faced migration is presented which sees the variables of socioeconomic status, knowledge of reservoir projects, vested interests and the degree of identification with place of affected persons as producing differential apprehension over moving. Differential apprehension is then seen as producing different attitudes toward the project which will influence the type of migration plans.

To test this model of forced migration, data were …

Evaluation Of The Social Impact Of Reservoir Construction On The Residential Plans Of Displaced Persons In Kentucky And Ohio, Richard L. Ludtke, Rabel J. Burdge

KWRRI Research Reports

The states of Kentucky and Ohio have numerous reservoir projects at various stages of planning and construction. Each of the projects produces substantial social impact for the residents of the area and particularly for those persons affected by a loss of property and homes. This impact is not uniform in that people respond differently to displacement and the methods of adjusting relocation are known to differ among people.

This research was initiated to develop and test a model for explaining migration under such conditions. The model includes a consideration of people's potential for transferring existing statuses to new residences, the …

An Evaluation Of Relationships Between Streamflow Patterns And Watershed Characteristics Through The Use Of Opset, L. Douglas James, William O. Thompson, Glendon Allen Ross, Earnest Y. Liou

KWRRI Research Reports

Selection among alternative flood control measures would be better informed if better information could be obtained on the marginal change in flood hazard associated with land use and other changes in the tributary watershed. Hydrologic modeling is the most promising approach to answering this question; however, the use of existing models is hampered by the absence of information correlating model parameters with physical characteristics of the watershed.

To deal with this situation, a method was developed for estimating the parameter values for the Stanford Watershed Model which best match recorded with simulated streamflows. Physical characteristics were measured for 17 rural …

Part I - Controlling The Soil Moisture Environment Of Transpiring Plants, Part Ii - Prediction Of Leaf Temperature Under Natural Atmospheric Conditions, Charles T. Haan, Billy J. Barfield, Robert Edling

KWRRI Research Reports

Part I

A technique for controlling the soil moisture potential in the root zone of transpiring plants was developed. The method uses the principles of unsaturated flow through a porous media to develop the desired moisture potential. In the case of non-steady state transpiration, the maximum possible fluctuation in the soil moisture potential can be determined by the techniques presented.

Part II

Two implicit leaf temperature prediction equations were derived from the energy balance approach. The equations define sensible and latent heat transfer from a plant population as a two step process:

1. Transfer between the plant leaf and the canopy …

Anticipations Of Change: A Socio-Economic Description Of A Kentucky County Before Reservoir Construction, Charles Robert Smith

KWRRI Research Reports

In the past the construction of large reservoirs in the United States has been evaluated largely in terms of the economic benefit they bring to the area where they are constructed and to the nation. Where human populations are involved, however, a host of social changes occur, many of which fundamentally alter the way of life of a people.

This report is part of a larger study which aims at analyzing the social costs and benefits of reservoir construction. The project is long range in that studies are to be carried out before, during, and after construction. This report concentrates …

Opset Program For Computerized Selection Of Watershed Parameter Values For The Stanford Watershed Model, Earnest Yuan-Shang Liou, L. Douglas James

KWRRI Research Reports

The advent of high-speed electronic computer made it possible to model complex hydrologic processes by mathematical expressions and thereby simulate streamflows from climatological data. The most widely used program is the Stanford Watershed Model, a digital parametric model of the land phase of the hydrologic cycle based on moisture accounting processes. It can be used to simulate annual or longer flow sequences at hourly time intervals. Due to its capability of simulating historical streamflows from recorded climatological data, it has a great potential in the planning and design of water resources systems. However, widespread use of the Stanford Watershed Model …

The Stanford Watershed Model: The Correlation Of Parameter Values Selected By A Computerized Procedure With Measurable Physical Characteristics Of The Watershed, Part 2, Glendon Allen Ross

KWRRI Research Reports

Soundly planned water resources development requires a knowledge of streamflow magnitudes and time patterns. Where recorded information is unavailable, water resources project design can be greatly improved by streamflow simulation.

This study is devoted to describing the application of a self-calibrating version of the Stanford Watershed Model to 17 rural Kentucky watersheds and two urbanizing watersheds. The required data for this version (OPSET) is tabulated and the data collection process is described. The watershed parameter values estimated by OPSET and independent numerical estimates of physical watershed characteristics are tabulated and correlated. The results should help in estimating parameter values for …
